To all whom it may concern Be it known that I, ANDR W EPPLER, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Welt-Winding Machines;.and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such-as will enable 10 others skilled in the art to which it appertains to make and use the same. 7

The present invention relates to certain new and useful improvements in weltwindbe more fully described in the following ing machines.

In the manufacture of welted shoes, the

welt is prepared by being first out, into strips, and passed through a grooving and beveling machine, then thoroughly moistened, after which it is ready to be fastened to the shoe. After the strip of welt has been passed through the grooving and beveling machine, it is coiled into a loose skein by the operator in order that it may be more conveniently immersed in the water. It is cu'stomary, when forming this skein by hand, ,for the operator to give the strip of welt a complete twist for each revolution of the skein. The necessity for'doing this will be easilyqseen when it is considered. that as the welt is being applied to the shoe the skein is laid upon the floorand a length of the welt is drawn up from the skein. If an initial twist in the opposite direction. were not put in the weltit would twist andform- B5 kinks at this time, seriously interfering with Q the work of the operator.

The object of this invention is to .wind the strip of welting into a loose coil or skein as it comes from. the groover andbeveler 0 and to automatically'give thestripo of weltingthe proper amount of twist in order that it shall unwind properly when the operator is applying it to the shoe. f

A further object of the invention is toflprovide a reel over which'the' welt may be wound and from which the welt may be easily removed at the conclusion 0f the winding operation.

Still further objects of the invention are to provide improvements in the various details of the winding machine tending to increase the efliciency and better the mode of operation of the machine. 7 v

Wit-h' the above ends, one feature of the invention contemplates the provision of a winding reel which revolves in a curved path about an axis substantially at right angles to its own axis, about which it is rotated, in order that the strip of welting mayv be twisted and at the same time wound into the winding operation but which may be collapsed to remove the coil of welting at the conclusion of the winding operation.

Still further features of the invention will specification.

In the accompanying drawings, illustrating the preferred form of the invention, Figure 1 illustrates a side elevation of the welt winder with a portion of the frame cut away and shown in section; Fig. 2 is a detail showing a plan view of the collapsible reel looking down upon the same from above, Fig. 3 is a sectional detail. illustrating the operating mechanism for collapsing the reel, Fig. 4 is a sectional detail showing the arrangement of the parts for-collapsing the reel and for rotating the same, and F ig. 5 is a diagrammatic view showing the course of the strip of welting as it is drawn by the welt winderfrom the power groover and beveler. r

In the illustrated embodiment of the invention, the winding reel 1 is rotatably mounted on a head 2 which is supported upon one end of the main driving shaft 3 v of the machine. The welt winding machine is positioned a short distance away from the 'groover and beveler 4 and in order that the strip of weltingmay be wound properly strip of welting. leading to it shall generate the surface of the cone.

As it would be difiicult to so accurately gage the speeds of the winding machine and the groover and beveler that they would be exactly alike at all times and as the speed with which the strip of welting is wound upon the reel increases as the diameter of the coil or skein of welting increases, it is deemed advisable to drive'thewelt winder at a slightly greater speed than the grooving and beveling machine and to provide a yielding driving connection in order that a certain amount of slip will occur when the tension upon the strip of welting becomes too great. The power is delivered from an exterior source to the main drive pulley 5 which is loosely mounted upon the drivmg shaft 3. The drive pulley is locked to the shaft 3 through the engagement of the. friction disk 6 mounted upon one side of the drive pulley and the friction disk 7 keyed to the end of the shaft 3. The friction disks are engaged with one another by moving the drive pulley 5 longitudinally of the shaft 3 by means of the sliding collar 8. The collar 8- is operated by a bell crank lever 9 pivotally mounted in the frame 10 of the machine and having one end fastened to the collar 8 and having the other end engaged by a coiled spring 11. Thecoiled spring 11 is a compression spring and bears at one end against the lower end of the bell crank 9 and l at its opposite end bears against a normally fixed screw 12 held in position by a lock nut 13. The tension of thespring may be varied, by adjusting the screw 12 in the frame 10. The normal action of the spring is to force the friction disks 6 and 7, comprising the clutch, into engagement with one another and lock the drive pulley to the shaft. A wedge block 14 is mounted upon the end of the shaft 16 and bears against the lower end of the bell crank 9 to move the bell crank againstthe action of the spring 11 in order to disengage the friction disks 6 is rotated the head 2 mounted upon the outer end of the shaft ,will rotate and cause the winding reel 1 to revolve in acircular path while at the same time the engagement of the gears 17 and 18 will rotate the winding 'reel about the axis of the shaft 20. The compound movement which is thus generated will give the proper twist to the strip of welting as it is wound. The winding reel proper comprises a base 21 having a plurality of arms 22 pivotally mounted upon it. In order that the skein of welting may be :the threads of the screw 25 is easily removed from the reel after it is wound thereon, means is provided for.collapsing the reel or moving the arms inwardly toward one another. The arms 22 are connected by links 23 with a central collar 24 which threadedly engages a screw'25. When the screw 25 is rotated to cause movement of the collar 24 in a vertical direction, the links 23 will draw the arms 22 inwardly owing to the fact that the arms 22 have their lower ends pivotally mounted below the point of connection of the links 23 with the arms and the skein may be then easily slipped from the reel. The end of the skein is fastened to the arms 22 at the beginning of the winding operation by providing a se ries of spring clips 26, one of which is mounted upon each arm and between which and the arm the end of the welting may be held. A rotation of the screw 25, in order to collapse the reel, is secured by mounting the screw upon the end of a shaft 27 which is rotatably mounted in the hollow shaft 20 and has a hand wheel 28 fastened to its lower end in order that the operator may conveniently rotate the screw 25.. A stop in the form of a flat disk 29 projecting beyond attached to the upper end of the screw and limits the movement of the collar 24 in one direction.

It is considered preferable to provide a guide which shall properly guide the strip of welting as it is wound upon the reel and which shall prevent the end of the strip from flapping about as it comes from the groover and beveler, loosening up andunwinding' the coils of welting which have been already wound upon the reel. The guide yieldably presses against the strip of welting so that the twist which is placed in it will pass under the guide and it may be stated at this time that although one twist may not occur in every convolution of the welting, if the twist is omitted in one convolution there will be a double twist in the following convolution and in-this way the total amount of necessary twist is imparted to the welt and inasmuch as there is a considerable length of welting unwound from the skein as the operator applies it to the shoe, the welting will always come to the operator in a straight form. The guide," which is provided in the present instance for maintaining the strip of welting in proper position, comprises an 'L-shaped bar 30 having one side positioned adjacent and parallel to the fingers 22 as theree'l rotates. The bar 30 is fastened in a block 31 loosely mounted upon the stud 32. The guide is held in yielding engagement with the strip of welting by a coiled spring 33 which engages the block 31 at one end and a fixed collar 34 at the other end. The bar 30 is held in proper position when the machine is inoperative by a pin 35 which is'mounted upon the outer end of the supporting bracket 36 and has its upper end engaging with the rear end of one side of the bar 30. The guide, as a whole, is mounted upon the supporting bracket 36 which is attached to the head 2 and travels in a circular path with thereel.

While the particulars described are well suited to one mechanical form of the inven-- tion, it is not to be understood that these particulars are essential since they may be variously modified within the skill of the artisan Without departing" from the true scope of the actual invention as defined by the claims.

What is claimed, is
